The udder inflammation results the increase of the somatic cells (SCC) in milk. The experiments were performed on a cattle farm in southern Hungary, where we analyzed 4490 data of 860 cows. This study aimed to answer how changes the milk production, milk fat percentage and milk protein percentage in the effect change of the somatic cell count. The cows are grouped according to the number of somatic cells. The milk production decreased in the groups when were high the SCC but, the milk protein and milk fat percent increased. The SCC was the highest between the 400th and 500th day of lactation
